HAND-MACHINE TO UNDERMINE COAL.

overcome the splashing of the water so that,

it will not come in contact with the light carried.

A further object of my invention is to provide a device so that with itsuse a miner .is not exposed to the water and dust of the mine and inaddition he is not scarring his hands by beating them against the coalas is the case in the event that a pick is employed.

A further feature of my invention is that in driving into a passage thatis narrow while only one man can work with a pick two machines can beemployed in its stead.

A further object of my invention is to provide a machine of the natureabove set forth that will be etficient in operation, comparatively cheapto manufacture and comparat ively simple in construction.

With the foregoing and other objects in view, my invention consists ofthe novel features of construction, combination and arrangements ofparts as ,are described in this specification, illustrated in theaccompanying drawings forming a part thereof, and particularly pointedout in the appended claims.

Reference being had to the drawings: Figure 1, is a side elevationalview of the device as it appears when in operation, Fig. 2, is a topplan view of the same, Fig. 3, is a perspective view of the rammer ordigger employed, with a part of the same removed, Fig. 1, is aperspective view of the board or center piece employed, Fig. 5, is adetail of the support for the rammer, Fig. 6, is a longitudinal verticalsectional view of the rammer or digger, and Fig. 7 is a perspective viewof the upper portion of the framework, illustrating the manner in whichthe same may be adjusted.

Serial No. 704,286.

Referring more particularly to the drawings in which like numeralsdesignate like parts throughout, my invention is described as follows: e

The device primarily consists of a framework or support 1, whichframework com prises two horizontal beams 2, resting upon the ground, avertica'l'beam 3, extending up from each of said horizontal beams 2, anda horizontal beam 4:, extending outward from each vertical beam 3, saidhorizontal beams 4, being provided with corresponding notches 5,arranged in spaced relation in the upper edge thereof. Braces 6, areprovided extending from each horizontal beam 4, to its respectivevertical beam 3.

Extending from one beam 4, to the opposite beam 4, and resting incorresponding notches 5 is a rod 7, held against movementby means ofpins 8, extending therethrough and into the beams. Extending from a ring9, at the center of said rod is a chain 10, which chain has two separateextensions 11, said extensions provided with rings 12 at their outerends, each of said rings engaging 80 v a. projection 13 formed upon theends of the support 1 1 of the rammer or digger 15, Said support is heldto the rammer or dig ger 15 by means of nut and bolt connection 16,extending through a perforation 17 in the support and a perforation-l8in the rammer or digger.

The rammer or digger is provided with longitudinal side pieces 19,forming to or integral with the base 20 thereof. ,The board or centerpiece 21, is received by the recess formed by the base 20-and the sidepieces 19, said center piece being provided centerpiece 21, and are heldagainst rear- 100 ward movement by the latter. Said spikes are providedwith heads 27 at their rear ends and are held against forward move mentby means of the cross bars 28 received by corresponding notches 29 orcorrespond- 105 ing notches 30. If the spikes wear off they areslid'forward, the rear cross bar 28 be ing removed from the notches 29,and received by the notches 30, the center piece 21 also being slidforward the ends of the head 110 22 thereof engaging notches 24, or 25as the case may be. The spikes may be arranged as is desired for. thepurpose, that is, the long spikes may be at the center or at the ends asis desired. i i

The entire frame 1, is made of wood except the sliding cap 31, Which capisfor the purpose of Wedging to the wall. according to the variations inheight of the coal. Taper,- ing spikes 32 are driven between the upperend of the vertical posts 3 and their respective caps, which actionpresses the cap upward against the coal and drives the spikehorizontally into the vertical wall of coal securing the device inposition. Said caps slide in recesses 33 in the side walls and theirrespective'posts, and they are secured to said posts by means of nut andbolt connections 34 extending through their lower ends and verticalslots 35 of h pos s i It w ill be seen that the center piece 21 is heldin position to therain iner or digger by means of a plurality of nut andbolt con V p a pris ng a frame, said frame comprising vernections 36extending through registering perforations 37 in the base 20, of the ran nierand oifthe centerpiece. At its rear end the ifafm nerford'iggefris provided a cross handle 38, for thepurpose or operating thesame. One man is'sutficient to; operate, the device by gripping saidhandle, but two men may operate the device if desired.

Although I have specifically described the novel" features ofconstruction, combination and arrangement of the several parts oi myinvention, yet I do not confine myself to such novel features ofconstruction, combination and arrangement of parts but reserve and. mayexercise the right to make such changes therein that do not depart fromthe spirit of the invention or scope of the appended claims.

Having described my invention what I claim as new, is:

'1. In a device of the kind described, a rannner said rammer consistingof a base and longitudinal side portions, a centerpiece received by therecess formed by the base and" side portions, spikes received by thatportion of the recess near the forward endof the. rammer, said spikeshaving a head, plurality of notches cut in the longitudinal walls of therammer, and said center piece provided with a cross head, the spikesheld againstrearward movement by abutting against the center piece andheld against forward movement by means of a cross piece engaging notchesin the longi-' tudinal side pieces of the, rammer and the heads of thespikes, said center piece held against movement by engaging correspond--ing notches in the sidewalls of the ram-mer, substantially as shown anddescribed.

2. In a device of the kind described comtical uprights, sliding capsfitting over the upper ends of the uprights and sliding in recessestherein, slots in each upright, nut and bolt connections, enteringthrough the lower ends of the caps and said slots, tapering spikes orwedges extending through the space between the upper ends of theuprights and said caps, substantially as shown and described.

testimony whereof I afiix signature in presence of two witnesses.
